ControlsOpening and closing
After switching off the ignition
When the remote control is removed or the igni-
tion is switched off, you can still operate the roof
for approx. 1 minute as long as no door has
been opened.
Pinch protection system
If the glass roof encounters an obstruction dur-
ing closing from approximately the middle of
the opening in the roof, or during closing from
the tilted position, the closing movement is
interrupted and the glass roof is opened again
slightly.
Despite the pinch protection system
check and clear the roof's travel path prior
to closing it; otherwise, the safety system might
fail to detect certain kinds of obstructions, such
as very thin objects, and the roof would con-
tinue closing. <
Closing without pinch protection
If there is an external danger, press the switch
forward past the resistan ce point and hold it
there. The roof closes without pinch protection.
Following interruptions in electrical
power supply
After a power failure, there is a possibility that
the glass roof can only be tilted. The system
must be initialized. BMW recommends having
this work performed at your BMW center.
Convertible: convertible top
The fully automatic top combines reliable
weather protection with simple and easy-to-
use operation.
The following tips will enhance your driving
pleasure in your Convertible:
> It is recommended that you close the con-
vertible top whenever the vehicle is parked.
The closed convertible top not only pro-
tects the vehicle interior from damage due
to unforeseen bad we ather, but also pro- vides a certain degree of protection against
theft. However, even when the top is
closed, valuables should
only be stored in
the locked trunk.
> Do not mount any roof rack systems on the
convertible top.
> If the top is opened while it is wet, e.g. after
driving in the rain, water may drip into the
trunk. If necessary, remove items from the
trunk beforehand to av oid water stains or
soiling.
At temperatures below +14 7/–10 6, do
not move the convertible top as this could
result in damage.
Do not keep the convertible top in the convert-
ible top box for longer than one day if it is wet;
otherwise, the moistu re may cause damage.
Do not place objects on the convertible top, as
otherwise they may fall off when you operate
the convertible top and cause damage or injury.
Never move the converti ble top when the roll-
over protection system is in the activated
position.
Always completely finish the operation of the
convertible top. Driving with the convertible top
incompletely opened or closed can result in
damage or injury.
Do not reach into the mechanism during the
opening or closing procedure. Keep children
away from the opening/closing path of the
convertible top.
For safety reasons, only operate the convertible
top while the vehicle is standing. <
While opening and closing, the convert-
ible top pivots upward. When operating
the convertible top in a garage, under a bridge,
etc., ensure that there are at least 6.5 ft/2 m of
headroom; otherwise, the vehicle may be
damaged. <

Wheels and tires
Mobility
Recommended tire brands
Certain makes of tire are recommended by
BMW for each tire size. They are marked with a
clearly visible BMW designation on the sidewall
of the tire.
When properly used, these tires meet the high-
est standards in terms of safety and handling
characteristics.
Special characteristics of winter tires
BMW recommends winter tires for driving on
winter roads or at temperatures below +45
7/
+7 6. Although all-season M+S tires provide
better winter traction th an summer tires, they
generally fail to provide the same levels of cold-
weather performance as winter tires.
Pay attention to speed
Always comply with the speed limit for the
winter tires mounted on your car; failure
to do so could result in tire damage and
accidents. <
If the car is capable of speeds higher than that
permitted for the winter ti res, a label stating the
maximum permitted speed for the mounted
tires must be displayed in your field of view.
Specialist tire dealers and your BMW center
can supply these labels.
Storage
Store wheels and tires in a cool, dry place with
as little exposure to light as possible. Always
protect tires against all co ntact with oil, grease
and fuels.
Do not exceed the maximum tire inflation
pressure indicated on th e sidewall of the tire.
Swapping wheels between axles
BMW advises against swapping wheels
between the front and rear axles, even if all tires
have the same size, as th is could impair driving
characteristics. If the tires are of mixed sizes,
swapping wheels between the axles is not
permissible.
Run-flat tires
The symbol identifying run- flat tires is a circle
with the letters RSC on the sidewall.
Run-flat tires comprise a conditionally self-
supporting tire and a special rim. The reinforce-
ment in the sidewalls en sures that the tire can
continue to be used su bject to certain restric-
tions, even if depressurized.
For information on continuing to drive with a flat
tire, refer to Indication of a flat tire on page92.
Snow chains
Only certain fine-link snow chains have been
tested by BMW, classified as safe for use and
recommended. Consult your BMW center for
more information. Snow chains must be
mounted in pairs and on the rear wheels only.
Observe the manufacturer's instructions when
mounting snow chains. Do not exceed a speed
of 30 mph/50 km/h with chains.
Do not initialize the Flat Tire Monitor if
snow chains are mounted; otherwise, the
instrument might issue an incorrect reading.
When driving with snow chains, you may find it
helpful to activate DT C temporarily, refer to
page 89.<
